Drive Pinion

Height Adjustment

NOTE: If the drive pinion and ring gear are replaced
(always as a set), the height has to be adjusted.

Select the proper shim as follows:
First, calculate the difference in size between the old
shim and the new pinion.

The last number (see ill.) on each pinion is the plus (+) or

minus (-) tolerance in thousands of a millimeter. So, a
pinion with +20 is 0.02 mm larger and a pinion with - 20
is 0.02 mm smaller.

1. If the number on the old pinion is a plus (+), add it

to the old shim thickness. If it is a minus (-), sub-
tract it from the old shim thickness.

2. If the number on the new pinion is a plus (+), sub-

tract it from the number you got in step 1. If it is a

minus (-), add it to the step 1 number.

3. Select the shim that is closest (but not more than)

the final number you got from steps 1 and 2.

ETCHED MARK

eg: A1-1

Example 1:

Old shim: 2.00 mm thickness
Old pinion: +20 (0.02 mm)

New pinion: -10 (-0.01 mm)

2.00 + 0.02 + 0.01 = 2.03

Select the 2.03 mm (0.0799 in) new shim.

Example 2:

Old shim: 1.70 mm thickness
Old pinion: -10 (-0.01 mm)
New pinion: -20 (-0.02 mm)

1.70-0.01 +0.02 = 1.71

Select the 1.70 mm (0.0669 in) new shim.

Ring Gear Tooth Contact

Ring Gear Backlash

Adjustment

1) Correct Tooth Contact

2) Toe Contact

Use a thinner drive pinion shim (43 mm thrust

shim) to move the drive pinion away from the ring
gear.

3) Heel Contact

Use a thicker drive pinion shim (43 mm thrust
shim) to move the drive pinion toward the ring
gear.

4) Flank Contact

To move the ring gear away from the drive pin-

ion, use a thicker side bearing shim (79.5 mm

thrust shim) on the drive pinion side and a thinner

one on the ring gear side.

NOTE: Recheck backlash after replacing the side
bearing shims. If out of specification, adjust as
described under Toe Contact.

5) Face Contact

To move the ring gear toward the drive pinion,

use a thinner side bearing shim (79.5 mm thrust
shim) on the drive pinion side and a thicker one
on the ring gear side.

NOTE: Recheck backlash after replacing the side
bearing shims. If out of specification, adjust as
described under Heel Contact.

Adjustment

1. If the backlash exceeds the standard, correct by

decreasing the shim thickness on one side and

increasing the thickness of the other shim the same

amount.

NOTE:
• The total thickness of both shims must still equal

the total thickness of the original shims.

• If there is too much backlash, move the ring gear

toward the drive pinion. If there is not enough

backlash, move the ring gear away from the
drive pinion.

2. After adjustment, recheck backlash (see page,
